Abstract

This paper presents an approach for an Enhanced Image Compression Method using Partial EZW Algorithm. This is based on the progressive image compression algorithm, EZW which is an extension of Shapiro’s embedded Zero tree Wavelet Algorithm. The proposed Partial EZW Algorithm overcomes the difficulty of EZW that loses its efficiency in transmitting lower bit planes. In this paper, we include integer wavelet transformation and region of interest coding to Partial EZW and hence make it more superior to EZW and SPIHT Algorithm and it is proved with the results.
